Translating 'はじまりはじまり' into English captures the playful repetition in the title while adapting its nuance. 'Beginning, Beginning' feels too literal, whereas 'It Begins, It Begins' carries more rhythmic energy, mirroring the original's celebratory tone. The song's lyrics often revolve around fresh starts and cyclical themes, so phrases like 'Here We Go Again' might work contextually, though it loses some poetic symmetry.
Cultural context matters too—the phrase evokes anime OP tropes where characters literally shout about new adventures (think 'One Piece' openings). A looser translation like 'The Start of Something New' could resonate with international fans familiar with Disney's 'High School Musical', creating subconscious familiarity. The challenge lies in preserving both the childlike excitement and the subtle meta-awareness present in many J-pop songs.
